The Sexketchbook's First Encounter
The receptionist greeted me with a warm smile the moment I stepped into the art academy to register.

Fair skin, bright sparkling eyes, and thick, plump lips. Her orange hair perfectly complemented her radiant smile, and she wore a refreshing, fruity perfume that tickled my nose.
Just looking at her made me want to grab her by the hair and fuck her senseless.
‘Wow… this bitch looks fucking delicious. I want to shove my cock right into that friendly little mouth of hers.’
“Do you have any prior art experience? Have you drawn before?”
Her voice was gentle and kind, but the way her shirt stretched tight across her massive tits was downright aggressive. A hint of her pink bra peeked out from between those glorious mounds.
‘Pink, huh? Like a bitch in heat. I’d love to bend her over right here, academy be damned.’
My dick was already getting heavy between my legs.
I’d been famous back in high school for my massive horse cock, after all.
Still half-dazed, I gave mechanical answers until she led me to a small, empty classroom.
Class A
“The homeroom teacher will assign seats when she arrives,” the receptionist said politely.
“Thank you.”
“Oh, and since it’s your first day, you’ll need to buy a small sketchbook! There’s a big art supply store on the first floor.”
“Ah, got it…”
‘Holy shit… the very first girl I meet here is already making my dick twitch like crazy.’
I adjusted my now rock-hard cock and trudged down the stairs, replaying the image of her bouncing tits in my mind.

I’d loved drawing ever since I was a kid. But only after becoming an adult and escaping my family’s terrible financial situation could I finally afford to register at an art academy.
While my friends were enjoying freshman life at prestigious Seoul universities or even mediocre ones, I spent six straight months working day and night loading and unloading delivery trucks.
All those stories about MTs and campus life were just distant tales I heard through messenger.
“Don’t stay here too long. Once you’ve saved enough money, get the hell out. Go learn what you want to learn.”
Sassu, the twenty-nine-year-old senior I’d grown close to at the loading dock, often nagged me like a big brother while watching over my twenty-year-old self.
Those words must have stuck with me.
The day my bank account finally crossed twenty million won, I quit the sweat-soaked, muscle-aching job and came here to chase the dream of becoming an artist—the one I’d kept buried in my heart since childhood.
Having spent my entire twenties so far without a single girlfriend, rotting away on the labor site, my sex drive had grown monstrous. I was basically a walking sex demon.
Even after having wet dreams every morning, my erection refused to go down. I’d lie there for a full hour with my twenty-centimeter king dick throbbing. It was running at full power twenty-four seven.

“Welcome!”
The large art supply store that sold everything from pencils and brushes to every art supply imaginable was staffed by a short, cute employee with black permed hair and a blushing white face.
‘This one’s fucking adorable too. I could have some real fun with her.’
“Are all the sketchbooks here?”
“Yes~ They’re organized by size and purpose, so take your time looking around,” she answered cheerfully, her permed curls bouncing as she stepped away with a little giggle.
I slowly browsed the shelves. My eyes wandered across the colorful, flashy products until they suddenly stopped on one particular sketchbook.
It was covered in a thick layer of dust.
‘This thing must’ve been sitting here forever.’
Stuck in the corner, shabby and forgotten among all the glamorous options, it somehow reminded me of myself—left behind while everyone else went off to university and enjoyed their dazzling youth.
“I’ll take this one.”
At that moment, I had no idea that this carelessly chosen sketchbook would turn me into a true sex demon.
The art shop employee wiped the dust off with a tissue and gave me a bright smile.
“It somehow suits you perfectly, student! Hehe.”
That bashful smile on her blushing face made her look like an innocent, adorable girl.
‘Fuck, she’s so cute… Girls like her make me want to pound them senseless.’
**
I picked a seat in the corner and waited about thirty minutes. One by one, students in school uniforms started filing in.
‘They all seem pretty close already.’
Thankfully, they only gave me a quick glance before losing interest.
“Oh, you must be the new student! I’m Kim Hye-yeong.”
The woman who greeted me with a wide, beautiful smile was stunning. No—absolutely gorgeous.
She looked around 170cm tall with large breasts. Her long straight hair was tied up, giving her a very mature, model-like aura. Her tight top and skinny jeans clung to her body, doing everything possible to highlight her incredible figure.
“Nice to meet you. I’m Park Hansol.”
“Starting exam prep art as a retaker won’t be easy, but I’ll help you as much as I can! Don’t worry~”
Our Class A assistant teacher, Kim Hye-yeong.
Her perfume carried a sweet yet slightly bitter scent. Every time her hair brushed against my hand, my brain completely shut down. I couldn’t focus on a single word of her explanation.
And whenever she gently took my hand to correct my grip, the soft texture of her skin made me want to keep rubbing against it forever.
She handed me a large sheet of paper and enthusiastically explained everything from how to hold a pencil to shading techniques, but my mind was somewhere else entirely.
“For today, just look at this and try to copy it exactly!”
She demonstrated a smooth gradient from dark to light tone, gave me today’s homework, and turned to leave. Even her retreating figure was hypnotic—her ass swayed beautifully beneath that long hair, practically dancing with every step.
‘I want to fuck her first. That body is insane… I could probably cum four times inside her without breaking a sweat.’
About two hours passed.
Just as the repetitive, meaningless motions started to wear me out, the students all poured out of the classroom at once.
‘Break time, I guess?’
They quickly split into groups of friends, around twenty of them heading out to buy dinner or snacks.
The nervous excitement of finally learning art faded quickly. I was exhausted from concentrating so hard.
‘Drawing while standing is new to me. My legs are killing me… and my constantly hard dick hurts too.’
I flopped down into my chair. When my eyes wandered aimlessly, they landed on the ugly sketchbook I’d bought earlier.
‘Come to think of it, I haven’t even taken the plastic off yet.’
It had a hard black cover and soft inner pages.
‘It’s break time. Maybe I’ll draw something I actually want to draw for a bit.’
Ever since I was young, I loved drawing people. In particular, I was obsessed with figure drawing.
Once I hit puberty and discovered the opposite sex, I started drawing all the lewd scenes I hadn’t experienced yet to soothe my raging hormones.
From girls in their twenties to women in their fifties—I’d drawn so many that I’d probably sketched every possible female body type. As a result, my sexual appetite grew day by day, and I had zero preferences or pickiness.
—First the torso… legs… nah, let’s start with the breasts.
—Scratch scratch scribble
I was so used to drawing erotic art that I finished the sketch in under five minutes.

A rather perverted drawing: a woman grabbing her own breasts hard with both hands, her tongue hanging loosely as she drooled down onto her chest.
After finishing it in a flash, I started wondering whose face to give it.
The receptionist who had welcomed me first today suddenly came to mind.
‘Her name was… Jung Ga-eun, right?’
‘That orange hair and pale skin were really attractive… and those tits were just…’
I smirked to myself as I drew her face.
—Scratch scratch
The moment I finished her face, my cock grew heavy again.
This damn thing never gives me a break. I was about to stroke it when I suddenly remembered something.
‘Oh shit! My wallet!’
I’d taken it out to pay and then completely forgotten it in the consultation room, too distracted by her chest.
What if someone took it? Panicking, I bolted out of the classroom at full speed.
**
I wanted to get it back before break time ended.
I burst into the consultation room in a rush. The moment I lifted my head to at least nod in greeting, I froze in complete shock.
She was standing there exactly as I had drawn her—
both hands tightly squeezing her own breasts,
tongue hanging slack,
drool dripping down onto her chest
in the most perverted pose imaginable.

‘Holy fuck… it’s exactly what I drew…?’
The second I saw her, I spun around and practically fled the room.
‘Why the hell is she posing like that? Is she giving herself a massage or something? Damn, that’s so fucking hot.’
Even though I felt a rush of excitement, guilt quickly followed.
‘It feels like I secretly spied on her. I’ll come back after class to get my wallet. Please still be there…’
I hurried back to the classroom and stared at the sketchbook again.
‘It’s exactly the same pose I drew…’
The moment those words left my mouth, letters began slowly rising from the thick back cover of the notebook—letters that hadn’t been there before.

‘What the…?’
‘Did someone secretly doodle in my notebook?’
The classroom was still empty. It was just me and this ugly sketchbook.
‘Wait… does that mean it actually made her act it out? So that’s why she was like that earlier?’
‘No way… that can’t be real.’
I was shocked, but at the same time, I couldn’t deny that I wanted to see it again.
After a short internal debate, I decided to test it one more time.
‘Fine. Just once. Let’s try it once.’
This time I drew Jung Ga-eun completely naked, kneeling behind the information desk and seductively tempting me with her massive breasts. I gave her the sluttiest expression possible as she squeezed her tits.
‘Done.’
‘I’m just going to get my wallet. Yeah… just my wallet…’
Even though I kept telling myself it wouldn’t happen, I was secretly hoping it would. Guess that’s what happens when you’re a natural-born pervert.
I walked down the still-empty hallway, clutching my pounding heart, and turned into the consultation room.
The receptionist, Jung Ga-eun, was nowhere at the front desk.
What was driving me insane was what lay behind the information counter.
‘Back there…’
Was she really there, just like the sketchbook said? Kneeling naked with her shirt off?
“Is… anyone… there?”
I cautiously stepped deeper into the consultation room, where half the lights were turned off.
Silence.
‘Maybe no one’s here after all…’
But as the area behind the desk slowly came into view, I saw her knees first.
Jung Ga-eun was kneeling there completely naked, waiting for me.
She looked up with a shy, faint smile and began crawling toward me on all fours—like a wild bitch in heat.
Her face was filled with pure lust, as if she wanted me to fuck her right then and there.
I thought I was going to lose my mind.
The lewd sketch I had drawn was now ten—no, twenty times more erotic in real life, perfectly brought to life right before my eyes.
‘Holy shit… it actually works?’
My heart was hammering so hard I thought it would explode. I ran out again.
It took only a few minutes for my previously rock-hard erection to calm down from the sheer shock.
Once I calmed down, I ran straight back to the classroom to understand what the hell was going on.
Because that ugly sketchbook had suddenly become far more important than my wallet.
